Be it known that I, Tnouxs subject of the King of England,

evizes, in lViltshi-re, England vented certain new and usefulImprovements in .Mechanism -for Manufacturing Pneumatic Tires, of-whichthe following is a specification.

This invention is for mechanism for main ufaoturing tires and hasparticular reference to. the consolidation ofithe 'fabric composing thetire after the latter has been removed from the former? whereon it hasbeen: built up.

.As is well-known tires are often made by Storm, a residing at ,havemhaving the shape which the tire is finally to assume, then after thelayers of material have been superimposed the whole or part of thefabric in many cases requires to be consolidated. This may be done byrolling it. down while on the former but. the object of the presentinvention i-s to provide means for effecting. the consolidation,particularly ofthe edges of the tire, after the tire. has beenremovedfrom the former.

Theinvention is especially applicable to tires buiit'up of cords placedaround staples or pins, (hereinafter referred to as pins only) disposedat what. finally constitute the edges of-the tire and which pins areemployedto anchor the cords to the beads: is well-known, the pins forthis purpose are carried by the former in such way that they'ai'esufficiently firm to permit the build ingiup of the tire, but can bewithdrawn withv the tire after the building up has been efl'ected." Itis found that after laying thecord over the pins, so that they extendthrough and project beyond the cords, the latter require to be drivenhome upon the pins. This .dri'yn'ig "home consolidates the edges of theeparestliein'fipr the reception of. is and -asalready stated-,tdxeobject of the"present invention is to provide means for effecting the-'consolidat has been removed-from the ploymenh: for the purpose'oftreating-a tire after "itsremoval "from the former whereon'it'ha'sbeenbuilt up; of supportsthat sus end bet'ween them the portion of the tireto 8 operated upon, means for applying pres- Specification of LettersPatent.

The supports conveniently take the form of two rollers over which thetire is hung so that a slack portion is suspended between them and themeans for consolidating the fabric preferably take the form of a press--wi l roller that cooperates with a bedding roer.

F or operation upon th operate upon I they are setat a different an ire, that is the supporting rolle edge of the tire glefrom the sup portingrollers so as to correspond to the position the edgeof the tire assumes when carried on the supporting rollers and it willbe seen that the suspended portion of the tire being free, allows the edguided under the presser roller.

For treatingtires built scribed, the presser roller is constructed witha lip or edge that may bear upon the tire close to the pins. I I

The tire I which is to iscarried by supporting are pivoted at M M frameM each roller is divided at M to admit the frame. To pressthe materialof l the tire P home upon the pins F, a. pressing roller J .is employed.This roller has, a channel J which may eit-hei be provided bygroo-vil'ig the roller. sist ofa doubleroller having a space he: tweenthe. two parts that'providesthe requi' site rhannel; --The rolleriscarriedon a} be operated upon It and is situated The spindle J hasa'handle J tire that is suspended between the :two roll- R TENT F I E-sThese two rollers are situated in ge to be readily 1 up of cord asderollers M M that respectively to a or the roller may con 1 snndle J"vrotatably mounted. in a standard opposite that -part ofv the canbeturned; Opposite lithe J and set at a suitable angle ng roller L havinga bed- L This roller is rotatably mounted on a is controlled by a springL that always tends to move it in a direction away from the pressingroller J. That end of the spindle 1-1 remote from the standard Kis-screw-threaded as shown at K and threaded on to this screw-threadedportion is a wheel K ball-bearing K 'is introduced between the thatextends from the bedding roller L and is concentric with the spindle K.

The frame M" is hinged at M to a rocking arm N. This arm is pivoted at Nto the standard and has at one end engagement with a screw-threadedspindle N The spindle passes through a lug is on the standard K and hasat its upper end a handle N The spindle can rotate in the lug 7c and isprovided with collars N N on opposite 7 sides of it to prevent endwisedisplacement.

On the rocking arm N and concentric with 'the pivot N is a pointer orindicator 0 that registers against a. scale 0' on the standard K. I I

The operation of this apparatus is as follows :The detached tire I isplaced over the supporting rollers M, M which latter engage the concaveportion of the tire, that is, the inner side opposite the tread. Therollers M, M are then raised or lowered by rotating the spindle N in onedirection or the other by the handle N The rotation of the spindlecansesthat end of the arm N which is in "engagement with it to rise orfall according to the direction of the rotation and thereby the frame Mis lowered or raised. The adjustment of the supporting rollers has to besuch that the edge of the tire will lie easily upon the bedding rollerand theinner ends of the pins will enter the groove If of the same. Thisposition will be always the same for a given size of tire andconsetpiently the scale C) may be marked to represent various sizes sothat the operator may immediately adjust his machine by rotating thehandle N until the indicator O, which mores with the rocking arm N, isopposite the indication on the scale corresponding to the size of tireupon which he is to operate. H

Having adjusted the tire upon the machine. the wheel K is rotated insuch manner as to advance the bedding roller L toward the pressingroller J and the pins F of the tire are made to enter the channel J ofthe roller. When the bedding roller has been advanced sufficiently tobring the requisite pressure to bear upon the material, the roller J isrotated by means of the handle J This causes the roller to drive thetire around upon the bedding roller L and the supporting rollers M, Mwhereby the whole of the edge of the tire is passed in successionbetween the pressing and bedding rollers, the

wheel and a sleei'e If.

. posed to the bedding face whereon the suspended portion L of thelatter always presenting a firm backing'for the material, and thistogether with the groove L serves to present the material in properposition for the operation of the pressing roller. A fixed guide P isprovided on the feedside of the roller. The guide is slotted at P toallow the passage of the pins F so that the pins traversing the slot Pare, with the edge of the tire, brought by the guide into proper linewith the roller and its channel J as the tire is advanced to the roller.It will be seen that as the portion of the tire operated upon by theroller J is suspended between the rollers M M? and the whole tire isflexible, the part operated upon can be readily guided into place.
